HYDROENTANGLING JET STRIP DEVICE DEFINING AN ORIFICE

摘要

A hydroentangling jet strip device is provided, wherein such a device comprises a plate member having opposing sides and defining at least one nozzle orifice extending between the opposing sides. Each of the at least one nozzle orifice includes an axially-extending capillary portion having an aspect ratio between a length of the capillary portion and a diameter of the capillary portion, wherein the aspect ratio is less than about 0.70 so as to be capable of providing a cavitation-free constricted waterjet.
